I have a 94 Ford F150, 4.9 L four-wheel-drive. I pulled the ECM out and replace the capacitors and it took care of everything that was running weird on my pick up. My truck was stuck on high idle. Replacing the capacitors made this truck run great. Thank you for the video.
@@Purosanluispotosi in the distributor box, the #1 relay could be the issue, swap that relay with the horn relay ( the relays are the same) and test it. could be the issue
I'm wondering how big a mess it is to replace the box where the relays go. Mine was burned on one end when the power steering or cruise control caught fire.
Thank you for taking the time to show us! Hope your rebuilder took care of you, if he didn't I could solder new Capacitors in it for you. It's less than 5 dollars worth of parts.
Thanks for the great video. I lost fire with a check engine light. I got a code reader and read code 211 failed PIP circuit. I replaced the PIP sensor to return control to the ignition coil. But I found a comment that failing capacitors in the PCM can cause the same OBD1 code 211. I need to check/replace them so I don't end up on the roadside a third time.
So I just took mine out took 2hrs and lots of sweating and cussing. The computer was rusted and seized in the bracket on the inside, wd 40 and prying and pretty much destroying the computer I finally got it out, thankfully when I opened it up it did have a couple capacitors that were burned up so I didn't remove/ break it for no reason. But I have no idea how I'm going to put the new one in 🤷♂️ Ideally I would like to relocate it inside the cab. Also the nuts on mine were 11mm, 12mm will work but a little loose.
Clear and concise. Just a thought, I just learned that the PCM also controls the transmission after months of trying to figure out where the "TCM" was located..... If that could be dubbed in. Thanks!
The computer is an aluminum casing, the bracket it slides into is steel. I'd bet that there is corrosion holding it in, try wiggling it up and down, and maybe even gently prying with a flat head screwdriver
@mavsfabshop thanks I just had to beat it out from the inside. It was really corroded to the bracket. If I buy a computer from the parts store do I have to have it programmed or anything weird? Or should I just buy a soldering iron and re do the capacitor that's just tumbling around in there?
@@beavanutz8336 I'm not brave enough to try and solder it back together, but you could try it. If you buy one from the parts store, they'll need the Vin and most likely the Calibration code on the door jamb
